BRITS are braced for a biblical barrage of rain as a fortnight’s worth is set to bucket down on the UK today.
The Met Office has issued yellow warning for most of the country - with rainfall totals of 15-25mm likely across Britain.
There is also potential for some spots to see totals of 40-60 mm - almost half of November's average UK rainfall.
Higher levels look most likely in parts of Bristol, Bath and Northeast Somerset, Wiltshire and into South Gloucestershire.
Downpours will ease from the west during Thursday afternoon and evening - but some hill snow is possible, especially in parts of south Wales.
The Met Office warns flooding is likely, adding: "Periods of rain are expected to become widespread and locally heavy across parts of England and Wales through Thursday.
"Over western areas, particularly the higher ground of Wales, some snow is also likely, with local accumulations of a few cm possible.
"Rainfall totals of 15-30 mm are likely, with some spots, particularly higher ground, seeing isolated totals of 40-60 mm."
Brits have battled torrential downpours over the last few days - with large swathes of northern regions submerged underwater.
Severe flooding hit several areas in Yorkshire and the East Midlands last week - with areas around the River Don near Doncaster worst affected after the river burst its banks.
Around half the 700 residents of Fishlake, near Doncaster, left the village and those who stayed behind have faced waist-high floods.
Annie Hall, the former high sheriff of Derbyshire, died after she was swept away by water on Friday in Darley Dale, near Matlock.
The Environment Agency has told of more potential flooding to come, with dozens of alerts and warnings still in force across the country.
